Penns Creek

Penns Creek begins high on Paddy Mountain in Centre County, Pennsylvania, flowing eastward through a spectacular limestone valley before cutting through Penns Creek Gorge and eventually joining the Susquehanna River near Selinsgrove. The upper and middle sections of Penns Creek, roughly 60 miles of water from Coburn downstream to the town of Weikert, support one of the finest wild brown trout fisheries in the eastern United States.

The character of Penns Creek changes dramatically along its length. The upper section above Coburn is a smaller mountain freestone stream with pocket water and plunge pools holding eager wild brook trout and brown trout. As the creek flows past Coburn and enters the famous limestone valley section, it transforms into a medium-sized river (30-50 feet wide) with classic riffle-run-pool structure, undercut limestone banks, and meadow water that holds large, selective brown trout.

The most celebrated section is the no-harvest water from the lower boundary of the Poe Paddy State Park downstream approximately 5 miles. This catch-and-release stretch flows through the remote Penns Creek Gorge, accessible only by hiking or floating. The isolation and protective regulations produce exceptional fishing for wild brown trout averaging 10-14 inches with fish to 20 inches possible.

Penns Creek is justly famous for the Green Drake hatch, one of the most spectacular mayfly emergences in North America. During late May and early June, massive Ephemera guttulata mayflies emerge in the evenings, bringing every trout in the river to the surface for rare opportunities at large browns on size 10 dry flies. Beyond the Green Drake, Penns Creek supports outstanding Sulphur hatches, Trico spinner falls, terrestrial fishing, and consistent Blue Winged Olive emergences.

Access to Penns Creek varies by section. The upper water has good roadside access along PA Route 45. The middle section has numerous public access points and State Gamelands frontage. The lower gorge section requires hiking or floating to reach, which naturally limits pressure and preserves the wilderness character.

Penns Creek is a limestone-enriched freestone stream, combining the cold, clear water character of mountain freestone with the fertility and insect productivity of limestone spring creeks. Water clarity is generally excellent, with 3-6 feet of visibility during normal flows. The limestone influence maintains relatively stable water temperatures and slightly alkaline pH that supports abundant aquatic insect life.

The creek's substrate is predominantly clean gravel and small cobble with occasional limestone ledges and boulders. This diverse bottom provides excellent trout habitat and supports a rich insect community including multiple mayfly species (Green Drakes, Sulphurs, Hendricksons, Blue Winged Olives, Tricos), caddisflies, and stoneflies. Water temperatures remain in the ideal trout range (50-65 degrees F) throughout most of the season, though low summer flows can stress fish during heat waves.

The wild brown trout population is self-sustaining, with natural reproduction occurring throughout the system. Brook trout inhabit the upper headwater sections. The combination of limestone fertility, diverse habitat, and protective regulations in key sections produces quality wild trout fishing.
